Patent GB-2033271-A (GB)
Title: Continuous Casting Machine
IPC: B22D11/06
Filed: 1979-07-31
Abstract: The machine has a pair of endless flexible mold assemblies 94, 96, which include mold blocks abutting each other in end-to-end relationship and each having a channel in one face thereof, whereby cooperating straight sections of the assemblies of mold blocks form a continuous mold cavity, extending forward and downward from the inlet end at an angle. The length of mold blocks 106 in the upper assembly in the direction of casting are half or less than the length of the mold blocks 108 in the lower assembly and the blocks are indexed so that the abutting faces of the blocks of one assembly occur intermediately of the blocks of the other assembly to prevent heat dams. Endless metal strips may be positioned in the bottoms of the channels of the mold blocks to ensure a smooth casting surface and reduce wear of the mould. <IMAGE>

Title: Identification marking clear plastics articles
IPC: C09D11/02
Filed: 1979-08-11
Abstract: A fade resistant, visually undetectable identification mark is imparted to an optically clear plastics lens or article by providing a marking composition comprising a solid fluorescent dye and a liquid carrier material, causing the dye to become supersaturated in the carrier, applying the supersaturated composition in a selected pattern on the surface of an article to be marked, removing the carrier material from the composition to leave a solid residue of the fluorescent dye, and permanently incorporating the dye in a surface layer of the article by heating. The mark enables a manufacturer to identify a particular article as its product by exposing it to ultraviolet radiation. The marking composition preferably includes an inert sublimable solid diluent.

Patent GB-2067749-A (GB)
Title: Improvements in and Relating to Fire and Explosion Detection
IPC: G08B17/12
Filed: 1980-12-30
Abstract: A fire and explosion detection system for discriminating between radiation produced by a source of fire or explosion to be detected and radiation produced by a source of fire or explosion not to be detected, comprises two radiation detectors 10, 12 respectively responsive to the intensity of radiation in different wavelength bands to produce respective electrical outputs. Detector 12 responds to a wavelength band including 4.4 microns (to detect hydrocarbon fires). In one embodiment, the latter is relatively narrow and included by the band to which detector 10 responds which is relatively broad. In another embodiment, the bands of both detectors are relatively narrow, the band of detector 10 being at 1 micron. A rate of rise unit 22 and a threshold unit 24 responsive to detector 12 produce signals of one type when the rate of rise of, and the value of, the intensity of the radiation received by that detector exceed predetermined values. A ratio unit 16 measures the ratio of the intensities of the radiation respectively received by detectors 10 and 12 and produces a signal of the opposite type when the ratio indicates that the source of radiation is a fire or explosion to which the system is not to respond. An AND gate 36 produces a fire and explosion indicating output only when the signals of the first type exist in the absence of the signal of the opposite type. <IMAGE>

Title: Device for measuring inclination electrically
Inventor: D ARCY GEORGE PAUL
IPC: G01C9/06
Filed: 1981-11-13
Abstract: A device for measuring inclination comprises a vessel partly filled with mercury or some other flowable conductive liquid or fluent powder, the wall 1 or 2, of the vessel being provided with a series of parallel resistance strips which in the horizontal position of the vessel are equally immersed in the mercury (3). When the device is tilted, the resistances of the unimmersed parts of the strips vary and the difference between the maximum and minimum resistance is a measure of the inclination and the position of the maximum and minimum resistance is a measure of the direction of the inclination. The measurements of resistance may be fed to a micro- processor which can then extrapolate them into a sinusoidal form to give exact measurements of both the angle and direction of inclination. <IMAGE>
